FLEXIBLE PIPE-JOINT.

SPECIFICATION forming part of Letters Patent No. 409,216, dated August20, 1889.

Application filed April 4, 1887. Serial No. 233,588. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL IV. MAGEE, of the city, county, and State ofNew York, have invented certain new and useful Improvements in FlexiblePipe-Joints, of which the following is afull, clear, and exactdescription, whereby any one skilled in the art can make and use thesame.

My invention relates to the class of devices that are adapted for use onrigid pipes for the purpose of making the same flexible; and my objectis to provide a joint that while it is sufficiently yielding to make thepipe to which it is fitted practically flexible will remain at the sametime steam-tight.

My improvement consists in the combination of the body parts of thejoint, the one part having a groove to receive a projecting tongue onthe other, with a rod extending through and within the parts, wherebythey may be drawn firmly together and the packin g interposed betweenthe bearing-faces and it further consists in the combination, with thepipe system, of a railway-car terminating in a pipe made flexible by theuse of the within-described joint and terminating in a coupling ofpeculiar construction, as more particularly hereinafter described, andpointed out in the claim.

Referring to the accompanying drawings, Figure 1 is a detail side Viewof a jointed pipe made flexible by the use of my improved joint. Fig. 2is a detail face or plan view of the bearing-face of one part of thejoint. Fig. 3 is a diagram view of a coupled pipe made flexible by theuse of my improved joint.

The pipe-fittings that form the subjectunatter of my within-describedinvention are es pecially intended and are adapted for use on theheating or brake systems of railway-cars, and in the drawings the lettera denotes the steam-pipe, to the end of which, usually just under theplatform of the car, is secured the joint I). This joint I) is made upof the body parts 0 and (Z, the former being a curved joint of aquarter-turn and having on its lower end a bearing-face with an annularprojection c, and on the outside of this projection is a flatbearing-surface 0 The body part (Z, that is likewise a quarter-turnpiece or elbow, has on its bearing-face an annular socket (1, into whichthe projection c is adapted to fit. These body parts are held togetherby means of the bolt 6, that is secured to one part, as c, and extendsthrough the center of the joints, pass ing through the other body part(I, and projecting beyond it a sufficient distance to re ceive the clamping-nuts f f, and this bolt forms in part the pivot on which the twobody parts turn, although the joint is in part supported by theintermeshing parts 011 the bearing-face between the two body parts ofthe joint.

The packing g is located in the socket d, and another annularpackingg isplaced upon the bearing-surface 0 A screw-cap h is fitted upon the bodypart c, and has a screw-thread that is fitted upon a thread out upon theouter surface of the body part (Z, and the function of this screwcap isto aid in preserving the alignment of theparts and to keep the packing gin place, while also serving in a measure to hold the body partstogether.

The body part d is provided with a number of ducts 1', that are smallopenings leading from the steamway in the body part (Z backward into theannular chamber (1', and are intended to allow the steam to pass intocontact withand to moisten the packing in the chamber. a

In order to prevent the leakage of steam, the packing'f" is placedbetween the under surface of the nut f and a bearing-surface on the bodypart (1.

In adapting this joint for use on a car there are three lengths of pipebeyond the first joint, already described and shown in section in thedrawings, the length 7o standing in a horizontal position, the length Zin a vertical position, and the length m in a horizontal position whenthe couplings n are united; but at other times the weight of the jointor causes it to hang in a vertical position and allow the free outletthrough the pipe of any steam, vapor, or water.

Of course it will be understood that each of the joints 7t Z isconstructed as the other joint already described. The joint attached tothe end of the pipe a is operated when the cars are running on a curve,while the joints is and Z come into operation in uniting the pipes oncars of different heights, and they also provide for the varyingdistance between the cars that is caused by the different kinds ofcouplings used or by the movement of the cars around curves, the pipesusually lying on one side of the center of the car, so that when theyturn to the right one side of the coupling is extended, while the otheris contracted, and in turning to the left the reverse is the effect.

I claim as my improvement-- In combination with a number of lengths ofrigid pipe, a joint composed of a body part c, forming a quarter-turn,with its bearingface having an annular projection c, the body part d,with an annular socket d in its bearing-face, and the supplemental ducts41, leadin g from the annular chamber into the steamway, the bolt 6,rigidly secured within one part and extending through the opposite Wallof the other part and forming the central pivot of the joint, ascrew-cap h, and the ring-pack- 2o ing g and all substantially asdescribed.
